Apple has the right to continue restricting its operating systems to its own hardware thanks to a decision handed down by the Ninth Circuit Court of Appeals on Wednesday. Circuit Judge Mary Schroeder wrote in her opinion that Apple's Mac OS X licensing agreement was indeed enforceable against Psystar, which had sold non-Mac computers with Mac OS X installed.

My sense through all of this is that Apple is engaging in hardware protectionism through misapplication of the term "copyright infringement".

It's exactly what they are doing. They are a software company which design reasonable good software but instead of selling software make their money by forcing end-users to buy expensive and subpar hardware from them. It's like MS forcing you to buy their PCs and phones for 5x the real price.
